Justin Bieber Gets in Post-Church Shadow Boxing Session

Justin Bieber was so full of spirit that he just had to unload some of it on one of his unsuspecting friends by throwing some phony blows.

The singer was outside of Hillsong Church in Beverly Hills when he put on a little shadow boxing demonstration, he’s been seriously training over the past couple of years, and definitely has some skills.

Floyd Mayweather was even helping Bieber hone his fighting skills before their fallout.
